When Australia's swimmers roll into Glasgow from their Manchester training camp this weekend, the symbolism will be obvious.

They will arrive as a team.

Two years on from a dismal Olympic campaign, which yielded just one gold medal from the pool, Swimming Australia has clearly learnt from its mistakes.

"Of course no one wanted that to happen in London," says new head coach Jacco Verhaeren.

"But in a way when things like this happen people start thinking about new strategies, about choosing a new path to go. And that actually happened."

An independent report commissioned in the wake of London 2012 described the swimming squad as a "team of individuals", citing their staggered arrival to the Games as evidence.

It will be different this time around.

"Since London we've definitely become more of a team," says Alicia Coutts, who is returning to these Commonwealth Games as a reigning champion in five events.

"You know we were very disjointed in London and it is nice to be able to feel like you are really part of a team now and we've really been working on getting closer and being really supportive of everyone else around us."

Coutts was Australia's most successful swimmer in London, bringing home a gold medal, three silver and a bronze. But she admits she considered quitting the sport in the aftermath.

Last year another swimmer, Matt Targett, was reprimanded for bullying her at a tri-series meet in Perth.

Targett became the face of the malaise gripping the sport.

Apart from the incident involving Coutts, he was also revealed as the ringleader of a controversial pre-Olympic "bonding" session.

He and fellow members of the men's 4 x 100m freestyle relay team were fined after admitting to misusing the sedative Stilnox and pestering other athletes. He's no longer part of the squad.

One of the men set to replace him, 22-year-old Kenneth To, says the new relay team has put the past behind it.

"It's a huge honour to be in that team," he says.

"We have a lot of history performing at the highest level with that team winning medals and doing our country proud," he says.

"I think Swimming Australia has done a great job to change the culture of the sport.

"It's been a really big focus the last one or two years since London and I think we've come an extraordinarily long way."

He credits Verhaeren, who took over the head coaching job in January, with making an immediate impact on the team's culture.

"Everyone in the team gives him a lot of respect, having coached so many Olympic champions from the Netherlands, and now coming to Australia and giving his knowledge to our team is something that's really special."
